参数

此方法没有任何参数。

返回值

string | null

示例

从三次贝塞尔曲线命令中提取控制点。

// Displays all bezier control points coordinates in spreadsheet cells.
let worksheet = Api.GetActiveSheet();
let customGeometry = Api.CreateCustomGeometry();
let path = customGeometry.AddPath();
path.SetWidth(100 * 36000);
path.SetHeight(100 * 36000);
path.MoveTo(0, 50 * 36000);
path.CubicBezTo(0, 0, 50 * 36000, 0, 50 * 36000, 50 * 36000);
path.QuadBezTo(100 * 36000, 50 * 36000, 100 * 36000, 100 * 36000);
path.ArcTo(50 * 36000, 50 * 36000, 0, 10800000);
path.Close();
let cmd = path.GetCommand(1);
worksheet.GetRange("A10").SetValue("CP1: (" + cmd.GetX0() + ", " + cmd.GetY0() + ")");
worksheet.GetRange("A11").SetValue("CP2: (" + cmd.GetX1() + ", " + cmd.GetY1() + ")");
worksheet.GetRange("A12").SetValue("End: (" + cmd.GetX2() + ", " + cmd.GetY2() + ")");
let fill = Api.CreateSolidFill(Api.RGB(100, 150, 200));
let stroke = Api.CreateStroke(18000, Api.CreateSolidFill(Api.RGB(50, 75, 100)));
let shape = worksheet.AddShape("rect", 60 * 36000, 60 * 36000, fill, stroke, 3, 0, 2, 0);
shape.SetGeometry(customGeometry);
